The features and advantages of the embodiments will become more apparent from the detailed description set forth below when taken in conjunction with the drawings, in which like reference characters identify corresponding elements throughout. In the drawings, like reference numbers generally indicate identical, functionally similar, and/or structurally similar elements.

DETAILED DESCRIPTION

The following detailed description refers to the accompanying drawings. The same reference numbers may be used in different drawings to identify the same or similar elements. In the following description, for purposes of explanation and not limitation, specific details are set forth such as particular structures, architectures, interfaces, techniques, etc. in order to provide a thorough understanding of the various aspects of various embodiments. However, it will be apparent to those skilled in the art having the benefit of the present disclosure that the various aspects of the various embodiments may be practiced in other examples that depart from these specific details. In certain instances, descriptions of well-known devices, circuits, and methods are omitted so as not to obscure the description of the various embodiments with unnecessary detail. For the purposes of the present document, the phrase “A or B” means (A), (B), or (A and B).

There are many performance measurements defined, and thus reporting the values for all of the measurements requires that enough network bandwidth be available. Also, processing the values of all of the measurements needs certain processing capacity. For some measurements, operator and/or consumer may not need to see their values all the time, but just need to see when their values reach certain thresholds for the granularity period. Therefore, a threshold monitoring service is defined for performance management of 5G networks including network slicing.

The measurements to be collected can be configured via network resource models (NRMs), therefore, the management of threshold monitoring can be supported via NRMs. Some embodiments of this disclosure provide methods and systems for performance threshold monitoring. The performance threshold monitoring provides an efficient way for performance measurement (PM) of the networks.

ThresholdMonitoringCapability

A ThresholdMonitoringCapability Information Object Class (IOC) represents the capability of threshold monitoring(s) allowed to be created by <<IOC>>ThresholdMonitoring to monitor some or all of the measurements identified by Measurements<<datatype>>.

This IOC instance provides the capability of the threshold monitoring(s) allowed to be created for the measurements of the (tree) nodes of a name-containment tree whose top (tree) node is the IOC instance name-containing the <<IOC>>ThresholdMonitoringCapability instance. In case one instance (say A) of this IOC is contained by a tree node (say X), and another instance (say B) of this IOC is contained by a subordinate tree node (of tree node X), the instance (B) of this IOC contained by the subordinate tree node (Y) prevail.

According to some embodiments, instance of this IOC are not created nor deleted by a consumer. It is created and deleted by the producer. According to some embodiments, table below illustrates the attributes of this IOC:

Systems and Implementations

FIG. 3 illustrates an example architecture of a system 300 of a network, in accordance with various embodiments. The following description is provided for an example system 300 that operates in conjunction with the LTE system standards and 5G or NR system standards as provided by 3GPP technical specifications. However, the example embodiments are not limited in this regard and the described embodiments may apply to other networks that benefit from the principles described herein, such as future 3GPP systems (e.g., Sixth Generation (6G)) systems, IEEE 802.16 protocols (e.g., WMAN, WiMAX, etc.), or the like.

As shown by FIG. 3, the system 300 includes UE 301 a and UE 301 b (collectively referred to as “UEs 301” or “UE 301”). In this example, UEs 301 are illustrated as smartphones (e.g., handheld touchscreen mobile computing devices connectable to one or more cellular networks), but may also comprise any mobile or non-mobile computing device, such as consumer electronics devices, cellular phones, smartphones, feature phones, tablet computers, wearable computer devices, personal digital assistants (PDAs), pagers, wireless handsets, desktop computers, laptop computers, in-vehicle infotainment (IVI), in-car entertainment (ICE) devices, an Instrument Cluster (IC), head-up display (HUD) devices, onboard diagnostic (OBD) devices, dashtop mobile equipment (DME), mobile data terminals (MOTs), Electronic Engine Management System (EEMS), electronic/engine control units (ECUs), electronic/engine control modules (ECMs), embedded systems, microcontrollers, control modules, engine management systems (EMS), networked or “smart” appliances, MTC devices, M2M, IoT devices, and/or the like.

In some embodiments, any of the UEs 301 may be IoT UEs, which may comprise a network access layer designed for low-power IoT applications utilizing short-lived UE connections. An IoT UE can utilize technologies such as M2M or MTC for exchanging data with an MTC server or device via a PLMN, ProSe or D2D communication, sensor networks, or IoT networks. The M2M or MTC exchange of data may be a machine-initiated exchange of data. An IoT network describes interconnecting IoT UEs, which may include uniquely identifiable embedded computing devices (within the Internet infrastructure), with short-lived connections. The IoT UEs may execute background applications (e.g., keep-alive messages, status updates, etc.) to facilitate the connections of the IoT network.

The UEs 301 may be configured to connect, for example, communicatively couple, with an or RAN 310. In embodiments, the RAN 310 may be an NG RAN or a 5G RAN, an E-UTRAN, or a legacy RAN, such as a UTRAN or GERAN. As used herein, the term “NG RAN” or the like may refer to a RAN 310 that operates in an NR or 5G system 300, and the term “E-UTRAN” or the like may refer to a RAN 310 that operates in an LTE or 4G system 300. The UEs 301 utilize connections (or channels) 303 and 304, respectively, each of which comprises a physical communications interface or layer (discussed in further detail below).

In this example, the connections 303 and 304 are illustrated as an air interface to enable communicative coupling, and can be consistent with cellular communications protocols, such as a GSM protocol, a CDMA network protocol, a PTT protocol, a POC protocol, a UMTS protocol, a 3GPP LTE protocol, a 5G protocol, a NR protocol, and/or any of the other communications protocols discussed herein. In embodiments, the UEs 301 may directly exchange communication data via a ProSe interface 305. The ProSe interface 305 may alternatively be referred to as a SL interface 305 and may comprise one or more logical channels, including but not limited to a PSCCH, a PSSCH, a PSDCH, and a PSBCH.

The UE 301 b is shown to be configured to access an AP 306 (also referred to as “WLAN node 306,” “WLAN 306,” “WLAN Termination 306,” “WT 306” or the like) via connection 307. The connection 307 can comprise a local wireless connection, such as a connection consistent with any IEEE 802.11 protocol, wherein the AP 306 would comprise a wireless fidelity (Wi-Fi®) router. In this example, the AP 306 is shown to be connected to the Internet without connecting to the core network of the wireless system (described in further detail below). In various embodiments, the UE 301 b, RAN 310, and AP 306 may be configured to utilize LWA operation and/or LWIP operation. The LWA operation may involve the UE 301 b in RRC_CONNECTED being configured by a RAN node 311 a-b to utilize radio resources of LTE and WLAN. LWIP operation may involve the UE 301 b using WLAN radio resources (e.g., connection 307) via IPsec protocol tunneling to authenticate and encrypt packets (e.g., IP packets) sent over the connection 307. IPsec tunneling may include encapsulating the entirety of original IP packets and adding a new packet header, thereby protecting the original header of the IP packets.

The RAN 310 can include one or more AN nodes or RAN nodes 311 a and 311 b (collectively referred to as “RAN nodes 311” or “RAN node 311”) that enable the connections 303 and 304. As used herein, the terms “access node,” “access point,” or the like may describe equipment that provides the radio baseband functions for data and/or voice connectivity between a network and one or more users. These access nodes can be referred to as BS, gNBs, RAN nodes, eNBs, NodeBs, RSUs, TRxPs or TRPs, and so forth, and can comprise ground stations (e.g., terrestrial access points) or satellite stations providing coverage within a geographic area (e.g., a cell). As used herein, the term “NG RAN node” or the like may refer to a RAN node 311 that operates in an NR or 5G system 300 (for example, a gNB), and the term “E-UTRAN node” or the like may refer to a RAN node 311 that operates in an LTE or 4G system 300 (e.g., an eNB). According to various embodiments, the RAN nodes 311 may be implemented as one or more of a dedicated physical device such as a macrocell base station, and/or a low power (LP) base station for providing femtocells, picocells or other like cells having smaller coverage areas, smaller user capacity, or higher bandwidth compared to macrocells.

In some embodiments, all or parts of the RAN nodes 311 may be implemented as one or more software entities running on server computers as part of a virtual network, which may be referred to as a CRAN and/or a virtual baseband unit pool (vBBUP). In these embodiments, the CRAN or vBBUP may implement a RAN function split, such as a PDCP split wherein RRC and PDCP layers are operated by the CRAN/vBBUP and other L2 protocol entities are operated by individual RAN nodes 311; a MAC/PHY split wherein RRC, PDCP, RLC, and MAC layers are operated by the CRAN/vBBUP and the PHY layer is operated by individual RAN nodes 311; or a “lower PHY” split wherein RRC, PDCP, RLC, MAC layers and upper portions of the PHY layer are operated by the CRAN/vBBUP and lower portions of the PHY layer are operated by individual RAN nodes 311. This virtualized framework allows the freed-up processor cores of the RAN nodes 311 to perform other virtualized applications. In some implementations, an individual RAN node 311 may represent individual gNB-DUs that are connected to a gNB-CU via individual F1 interfaces (not shown by FIG. 3). In these implementations, the gNB-DUs may include one or more remote radio heads or RFEMs (see, e.g., FIG. 6), and the gNB-CU may be operated by a server that is located in the RAN 310 (not shown) or by a server pool in a similar manner as the CRAN/vBBUP. Additionally or alternatively, one or more of the RAN nodes 311 may be next generation eNBs (ng-eNBs), which are RAN nodes that provide E-UTRA user plane and control plane protocol terminations toward the UEs 301, and are connected to a 5GC (e.g., CN 520 of FIG. 5) via an NG interface (discussed infra).

In V2X scenarios one or more of the RAN nodes 311 may be or act as RSUs. The term “Road Side Unit” or “RSU” may refer to any transportation infrastructure entity used for V2X communications. An RSU may be implemented in or by a suitable RAN node or a stationary (or relatively stationary) UE, where an RSU implemented in or by a UE may be referred to as a “UE-type RSU,” an RSU implemented in or by an eNB may be referred to as an “eNB-type RSU,” an RSU implemented in or by a gNB may be referred to as a “gNB-type RSU,” and the like. In one example, an RSU is a computing device coupled with radio frequency circuitry located on a roadside that provides connectivity support to passing vehicle UEs 301 (vUEs 301). The RSU may also include internal data storage circuitry to store intersection map geometry, traffic statistics, media, as well as applications/software to sense and control ongoing vehicular and pedestrian traffic. The RSU may operate on the 5.9 GHz Direct Short Range Communications (DSRC) band to provide very low latency communications required for high speed events, such as crash avoidance, traffic warnings, and the like. Additionally or alternatively, the RSU may operate on the cellular V2X band to provide the aforementioned low latency communications, as well as other cellular communications services. Additionally or alternatively, the RSU may operate as a Wi-Fi hotspot (2.4 GHz band) and/or provide connectivity to one or more cellular networks to provide uplink and downlink communications. The computing device(s) and some or all of the radiofrequency circuitry of the RSU may be packaged in a weatherproof enclosure suitable for outdoor installation, and may include a network interface controller to provide a wired connection (e.g., Ethernet) to a traffic signal controller and/or a backhaul network.

Any of the RAN nodes 311 can terminate the air interface protocol and can be the first point of contact for the UEs 301. In some embodiments, any of the RAN nodes 311 can fulfill various logical functions for the RAN 310 including, but not limited to, radio network controller (RNC) functions such as radio bearer management, uplink and downlink dynamic radio resource management and data packet scheduling, and mobility management.

In embodiments, the UEs 301 can be configured to communicate using OFDM communication signals with each other or with any of the RAN nodes 311 over a multicarrier communication channel in accordance with various communication techniques, such as, but not limited to, an OFDMA communication technique (e.g., for downlink communications) or a SC-FDMA communication technique (e.g., for uplink and ProSe or sidelink communications), although the scope of the embodiments is not limited in this respect. The OFDM signals can comprise a plurality of orthogonal subcarriers.

In some embodiments, a downlink resource grid can be used for downlink transmissions from any of the RAN nodes 311 to the UEs 301, while uplink transmissions can utilize similar techniques. The grid can be a time-frequency grid, called a resource grid or time-frequency resource grid, which is the physical resource in the downlink in each slot. Such a time-frequency plane representation is a common practice for OFDM systems, which makes it intuitive for radio resource allocation. Each column and each row of the resource grid corresponds to one OFDM symbol and one OFDM subcarrier, respectively. The duration of the resource grid in the time domain corresponds to one slot in a radio frame. The smallest time-frequency unit in a resource grid is denoted as a resource element. Each resource grid comprises a number of resource blocks, which describe the mapping of certain physical channels to resource elements. Each resource block comprises a collection of resource elements; in the frequency domain, this may represent the smallest quantity of resources that currently can be allocated. There are several different physical downlink channels that are conveyed using such resource blocks.

According to various embodiments, the UEs 301 a, 301 b and the RAN nodes 311 a, 311 b communicate data (for example, transmit and receive) data over a licensed medium (also referred to as the “licensed spectrum” and/or the “licensed band”) and an unlicensed shared medium (also referred to as the “unlicensed spectrum” and/or the “unlicensed band”). The licensed spectrum may include channels that operate in the frequency range of approximately 400 MHz to approximately 3.8 GHz, whereas the unlicensed spectrum may include the 5 GHz band.

To operate in the unlicensed spectrum, the UEs 301 a, 301 b and the RAN nodes 311 a, 311 b may operate using LAA, eLAA, and/or feLAA mechanisms. In these implementations, the UEs 301 a, 301 b and the RAN nodes 311 a, 311 b may perform one or more known medium-sensing operations and/or carrier-sensing operations in order to determine whether one or more channels in the unlicensed spectrum is unavailable or otherwise occupied prior to transmitting in the unlicensed spectrum. The medium/carrier sensing operations may be performed according to a listen-before-talk (LBT) protocol.

LBT is a mechanism whereby equipment (for example, UEs 301 a, 301 b, RAN nodes 311 a, 311 b, etc.) senses a medium (for example, a channel or carrier frequency) and transmits when the medium is sensed to be idle (or when a specific channel in the medium is sensed to be unoccupied). The medium sensing operation may include CCA, which utilizes at least ED to determine the presence or absence of other signals on a channel in order to determine if a channel is occupied or clear. This LBT mechanism allows cellular/LAA networks to coexist with incumbent systems in the unlicensed spectrum and with other LAA networks. ED may include sensing RF energy across an intended transmission band for a period of time and comparing the sensed RF energy to a predefined or configured threshold.

Typically, the incumbent systems in the 5 GHz band are WLANs based on IEEE 802.11 technologies. WLAN employs a contention-based channel access mechanism, called CSMA/CA. Here, when a WLAN node (e.g., a mobile station (MS) such as UE 301 a or 301 b, AP 306, or the like) intends to transmit, the WLAN node may first perform CCA before transmission. Additionally, a backoff mechanism is used to avoid collisions in situations where more than one WLAN node senses the channel as idle and transmits at the same time. The backoff mechanism may be a counter that is drawn randomly within the CWS, which is increased exponentially upon the occurrence of collision and reset to a minimum value when the transmission succeeds. The LBT mechanism designed for LAA is somewhat similar to the CSMA/CA of WLAN. In some implementations, the LBT procedure for DL or UL transmission bursts including PDSCH or PUSCH transmissions, respectively, may have an LAA contention window that is variable in length between X and Y ECCA slots, where X and Y are minimum and maximum values for the CWSs for LAA. In one example, the minimum CWS for an LAA transmission may be 9 microseconds (p); however, the size of the CWS and a MCOT (for example, a transmission burst) may be based on governmental regulatory requirements.

The LAA mechanisms are built upon CA technologies of LTE-Advanced systems. In CA, each aggregated carrier is referred to as a CC. A CC may have a bandwidth of 1.4, 3, 5, 10, 15 or 20 MHz and a maximum of five CCs can be aggregated, and therefore, a maximum aggregated bandwidth is 100 MHz. In FDD systems, the number of aggregated carriers can be different for DL and UL, where the number of UL CCs is equal to or lower than the number of DL component carriers. In some cases, individual CCs can have a different bandwidth than other CCs. In TDD systems, the number of CCs as well as the bandwidths of each CC is usually the same for DL and UL.

CA also comprises individual serving cells to provide individual CCs. The coverage of the serving cells may differ, for example, because CCs on different frequency bands will experience different pathloss. A primary service cell or PCell may provide a PCC for both UL and DL, and may handle RRC and NAS related activities. The other serving cells are referred to as SCells, and each SCell may provide an individual SCC for both UL and DL. The SCCs may be added and removed as required, while changing the PCC may require the UE 301 a, 301 b to undergo a handover. In LAA, eLAA, and feLAA, some or all of the SCells may operate in the unlicensed spectrum (referred to as “LAA SCells”), and the LAA SCells are assisted by a PCell operating in the licensed spectrum. When a UE is configured with more than one LAA SCell, the UE may receive UL grants on the configured LAA SCells indicating different PUSCH starting positions within a same subframe.

The PDSCH carries user data and higher-layer signaling to the UEs 301. The PDCCH carries information about the transport format and resource allocations related to the PDSCH channel, among other things. It may also inform the UEs 301 about the transport format, resource allocation, and HARQ information related to the uplink shared channel. Typically, downlink scheduling (assigning control and shared channel resource blocks to the UE 301 b within a cell) may be performed at any of the RAN nodes 311 based on channel quality information fed back from any of the UEs 301. The downlink resource assignment information may be sent on the PDCCH used for (e.g., assigned to) each of the UEs 301.

The PDCCH uses CCEs to convey the control information. Before being mapped to resource elements, the PDCCH complex-valued symbols may first be organized into quadruplets, which may then be permuted using a sub-block interleaver for rate matching. Each PDCCH may be transmitted using one or more of these CCEs, where each CCE may correspond to nine sets of four physical resource elements known as REGs. Four Quadrature Phase Shift Keying (QPSK) symbols may be mapped to each REG. The PDCCH can be transmitted using one or more CCEs, depending on the size of the DCI and the channel condition. There can be four or more different PDCCH formats defined in LTE with different numbers of CCEs (e.g., aggregation level, L=1, 2, 4, or 8).

Some embodiments may use concepts for resource allocation for control channel information that are an extension of the above-described concepts. For example, some embodiments may utilize an EPDCCH that uses PDSCH resources for control information transmission. The EPDCCH may be transmitted using one or more ECCEs. Similar to above, each ECCE may correspond to nine sets of four physical resource elements known as an EREGs. An ECCE may have other numbers of EREGs in some situations.

The RAN nodes 311 may be configured to communicate with one another via interface 312. In embodiments where the system 300 is an LTE system (e.g., when CN 320 is an EPC 420 as in FIG. 4), the interface 312 may be an X2 interface 312. The X2 interface may be defined between two or more RAN nodes 311 (e.g., two or more eNBs and the like) that connect to EPC 320, and/or between two eNBs connecting to EPC 320. In some implementations, the X2 interface may include an X2 user plane interface (X2-U) and an X2 control plane interface (X2-C). The X2-U may provide flow control mechanisms for user data packets transferred over the X2 interface, and may be used to communicate information about the delivery of user data between eNBs. For example, the X2-U may provide specific sequence number information for user data transferred from a MeNB to an SeNB; information about successful in sequence delivery of PDCP PDUs to a UE 301 from an SeNB for user data; information of PDCP PDUs that were not delivered to a UE 301; information about a current minimum desired buffer size at the SeNB for transmitting to the UE user data; and the like. The X2-C may provide intra-LTE access mobility functionality, including context transfers from source to target eNBs, user plane transport control, etc.; load management functionality; as well as inter-cell interference coordination functionality.

In embodiments where the system 300 is a 5G or NR system (e.g., when CN 320 is an 5GC 520 as in FIG. 5), the interface 312 may be an Xn interface 312. The Xn interface is defined between two or more RAN nodes 311 (e.g., two or more gNBs and the like) that connect to 5GC 320, between a RAN node 311 (e.g., a gNB) connecting to 5GC 320 and an eNB, and/or between two eNBs connecting to 5GC 320. In some implementations, the Xn interface may include an Xn user plane (Xn-U) interface and an Xn control plane (Xn-C) interface. The Xn-U may provide non-guaranteed delivery of user plane PDUs and support/provide data forwarding and flow control functionality. The Xn-C may provide management and error handling functionality, functionality to manage the Xn-C interface; mobility support for UE 301 in a connected mode (e.g., CM-CONNECTED) including functionality to manage the UE mobility for connected mode between one or more RAN nodes 311. The mobility support may include context transfer from an old (source) serving RAN node 311 to new (target) serving RAN node 311; and control of user plane tunnels between old (source) serving RAN node 311 to new (target) serving RAN node 311. A protocol stack of the Xn-U may include a transport network layer built on Internet Protocol (IP) transport layer, and a GTP—U layer on top of a UDP and/or IP layer(s) to carry user plane PDUs. The Xn-C protocol stack may include an application layer signaling protocol (referred to as Xn Application Protocol (Xn-AP)) and a transport network layer that is built on SCTP. The SCTP may be on top of an IP layer, and may provide the guaranteed delivery of application layer messages. In the transport IP layer, point-to-point transmission is used to deliver the signaling PDUs. In other implementations, the Xn-U protocol stack and/or the Xn-C protocol stack may be same or similar to the user plane and/or control plane protocol stack(s) shown and described herein.

The RAN 310 is shown to be communicatively coupled to a core network—in this embodiment, core network (CN) 320. The CN 320 may comprise a plurality of network elements 322, which are configured to offer various data and telecommunications services to customers/subscribers (e.g., users of UEs 301) who are connected to the CN 320 via the RAN 310. The components of the CN 320 may be implemented in one physical node or separate physical nodes including components to read and execute instructions from a machine-readable or computer-readable medium (e.g., a non-transitory machine-readable storage medium). In some embodiments, NFV may be utilized to virtualize any or all of the above-described network node functions via executable instructions stored in one or more computer-readable storage mediums (described in further detail below). A logical instantiation of the CN 320 may be referred to as a network slice, and a logical instantiation of a portion of the CN 320 may be referred to as a network sub-slice. NFV architectures and infrastructures may be used to virtualize one or more network functions, alternatively performed by proprietary hardware, onto physical resources comprising a combination of industry-standard server hardware, storage hardware, or switches. In other words, NFV systems can be used to execute virtual or reconfigurable implementations of one or more EPC components/functions.

Generally, the application server 330 may be an element offering applications that use IP bearer resources with the core network (e.g., UMTS PS domain, LTE PS data services, etc.). The application server 330 can also be configured to support one or more communication services (e.g., VoIP sessions, PTT sessions, group communication sessions, social networking services, etc.) for the UEs 301 via the EPC 320.

In embodiments, the CN 320 may be a 5GC (referred to as “5GC 320” or the like), and the RAN 310 may be connected with the CN 320 via an NG interface 313. In embodiments, the NG interface 313 may be split into two parts, an NG user plane (NG-U) interface 314, which carries traffic data between the RAN nodes 311 and a UPF, and the S1 control plane (NG-C) interface 315, which is a signaling interface between the RAN nodes 311 and AMFs. Embodiments where the CN 320 is a 5GC 320 are discussed in more detail with regard to FIG. 5.

In embodiments, the CN 320 may be a 5G CN (referred to as “5GC 320” or the like), while in other embodiments, the CN 320 may be an EPC). Where CN 320 is an EPC (referred to as “EPC 320” or the like), the RAN 310 may be connected with the CN 320 via an S1 interface 313. In embodiments, the S1 interface 313 may be split into two parts, an S1 user plane (S1-U) interface 314, which carries traffic data between the RAN nodes 311 and the S-GW, and the S1-MME interface 315, which is a signaling interface between the RAN nodes 311 and MMEs. An example architecture wherein the CN 320 is an EPC 320 is shown by FIG. 4.

FIG. 4 illustrates an example architecture of a system 400 including a first CN 420, in accordance with various embodiments. In this example, system 400 may implement the LTE standard wherein the CN 420 is an EPC 420 that corresponds with CN 320 of FIG. 3. Additionally, the UE 401 may be the same or similar as the UEs 301 of FIG. 3, and the E-UTRAN 410 may be a RAN that is the same or similar to the RAN 310 of FIG. 3, and which may include RAN nodes 311 discussed previously. The CN 420 may comprise MMEs 421, an S-GW 422, a P-GW 423, a HSS 424, and a SGSN 425.

The MMEs 421 may be similar in function to the control plane of legacy SGSN, and may implement MM functions to keep track of the current location of a UE 401. The MMEs 421 may perform various MM procedures to manage mobility aspects in access such as gateway selection and tracking area list management. MM (also referred to as “EPS MM” or “EMM” in E-UTRAN systems) may refer to all applicable procedures, methods, data storage, etc. that are used to maintain knowledge about a present location of the UE 401, provide user identity confidentiality, and/or perform other like services to users/subscribers. Each UE 401 and the MME 421 may include an MM or EMM sublayer, and an MM context may be established in the UE 401 and the MME 421 when an attach procedure is successfully completed. The MM context may be a data structure or database object that stores MM-related information of the UE 401. The MMEs 421 may be coupled with the HSS 424 via an Sha reference point, coupled with the SGSN 425 via an S3 reference point, and coupled with the S-GW 422 via an S11 reference point.

The SGSN 425 may be a node that serves the UE 401 by tracking the location of an individual UE 401 and performing security functions. In addition, the SGSN 425 may perform Inter-EPC node signaling for mobility between 2G/3G and E-UTRAN 3GPP access networks; PDN and S-GW selection as specified by the MMEs 421; handling of UE 401 time zone functions as specified by the MMEs 421; and MME selection for handovers to E-UTRAN 3GPP access network. The S3 reference point between the MMES 421 and the SGSN 425 may enable user and bearer information exchange for inter-3GPP access network mobility in idle and/or active states.

The HSS 424 may comprise a database for network users, including subscription-related information to support the network entities' handling of communication sessions. The EPC 420 may comprise one or several HSSs 424, depending on the number of mobile subscribers, on the capacity of the equipment, on the organization of the network, etc. For example, the HSS 424 can provide support for routing/roaming, authentication, authorization, naming/addressing resolution, location dependencies, etc. An S6a reference point between the HSS 424 and the MMEs 421 may enable transfer of subscription and authentication data for authenticating/authorizing user access to the EPC 420 between HSS 424 and the MMES 421.

The S-GW 422 may terminate the S1 interface 313 (“S1-U” in FIG. 4) toward the RAN 410, and routes data packets between the RAN 410 and the EPC 420. In addition, the S-GW 422 may be a local mobility anchor point for inter-RAN node handovers and also may provide an anchor for inter-3GPP mobility. Other responsibilities may include lawful intercept, charging, and some policy enforcement. The S11 reference point between the S-GW 422 and the MMES 421 may provide a control plane between the M_MEs 421 and the S-GW 422. The S-GW 422 may be coupled with the P-GW 423 via an S5 reference point.

The P-GW 423 may terminate an SGi interface toward a PDN 430. The P-GW 423 may route data packets between the EPC 420 and external networks such as a network including the application server 330 (alternatively referred to as an “AF”) via an IP interface 325 (see e.g., FIG. 3). In embodiments, the P-GW 423 may be communicatively coupled to an application server (application server 330 of FIG. 3 or PDN 430 in FIG. 4) via an IP communications interface 325 (see, e.g., FIG. 3). The S5 reference point between the P-GW 423 and the S-GW 422 may provide user plane tunneling and tunnel management between the P-GW 423 and the S-GW 422. The S5 reference point may also be used for S-GW 422 relocation due to UE 401 mobility and if the S-GW 422 needs to connect to a non-collocated P-GW 423 for the required PDN connectivity. The P-GW 423 may further include a node for policy enforcement and charging data collection (e.g., PCEF (not shown)). Additionally, the SGi reference point between the P-GW 423 and the packet data network (PDN) 430 may be an operator external public, a private PDN, or an intra operator packet data network, for example, for provision of IMS services. The P-GW 423 may be coupled with a PCRF 426 via a Gx reference point.

PCRF 426 is the policy and charging control element of the EPC 420. In a non-roaming scenario, there may be a single PCRF 426 in the Home Public Land Mobile Network (HPLMN) associated with a UE 401's Internet Protocol Connectivity Access Network (IP-CAN) session. In a roaming scenario with local breakout of traffic, there may be two PCRFs associated with a UE 401's IP-CAN session, a Home PCRF (H-PCRF) within an HPLMN and a Visited PCRF (V-PCRF) within a Visited Public Land Mobile Network (VPLMN). The PCRF 426 may be communicatively coupled to the application server 430 via the P-GW 423. The application server 430 may signal the PCRF 426 to indicate a new service flow and select the appropriate QoS and charging parameters. The PCRF 426 may provision this rule into a PCEF (not shown) with the appropriate TFT and QCI, which commences the QoS and charging as specified by the application server 430. The Gx reference point between the PCRF 426 and the P-GW 423 may allow for the transfer of QoS policy and charging rules from the PCRF 426 to PCEF in the P-GW 423. An Rx reference point may reside between the PDN 430 (or “AF 430”) and the PCRF 426.

FIG. 5 illustrates an architecture of a system 500 including a second CN 520 in accordance with various embodiments. The system 500 is shown to include a UE 501, which may be the same or similar to the UEs 301 and UE 401 discussed previously; a (R)AN 510, which may be the same or similar to the RAN 310 and RAN 410 discussed previously, and which may include RAN nodes 311 discussed previously; and a DN 503, which may be, for example, operator services, Internet access or 3rd party services; and a 5GC 520. The 5GC 520 may include an AUSF 522; an AMF 521; a SMF 524; a NEF 523; a PCF 526; a NRF 525; a UDM 527; an AF 528; a UPF 502; and a NSSF 529.

The UPF 502 may act as an anchor point for intra-RAT and inter-RAT mobility, an external PDU session point of interconnect to DN 503, and a branching point to support multi-homed PDU session. The UPF 502 may also perform packet routing and forwarding, perform packet inspection, enforce the user plane part of policy rules, lawfully intercept packets (UP collection), perform traffic usage reporting, perform QoS handling for a user plane (e.g., packet filtering, gating, UL/DL rate enforcement), perform Uplink Traffic verification (e.g., SDF to QoS flow mapping), transport level packet marking in the uplink and downlink, and perform downlink packet buffering and downlink data notification triggering. UPF 502 may include an uplink classifier to support routing traffic flows to a data network. The DN 503 may represent various network operator services, Internet access, or third party services. DN 503 may include, or be similar to, application server 330 discussed previously. The UPF 502 may interact with the SMF 524 via an N4 reference point between the SMF 524 and the UPF 502.

The AUSF 522 may store data for authentication of UE 501 and handle authentication-related functionality. The AUSF 522 may facilitate a common authentication framework for various access types. The AUSF 522 may communicate with the AMF 521 via an N12 reference point between the AMF 521 and the AUSF 522; and may communicate with the UDM 527 via an N13 reference point between the UDM 527 and the AUSF 522. Additionally, the AUSF 522 may exhibit an Nausf service-based interface.

The AMF 521 may be responsible for registration management (e.g., for registering UE 501, etc.), connection management, reachability management, mobility management, and lawful interception of AMF-related events, and access authentication and authorization. The AMF 521 may be a termination point for the an N11 reference point between the AMF 521 and the SMF 524. The AMF 521 may provide transport for SM messages between the UE 501 and the SMF 524, and act as a transparent proxy for routing SM messages. AMF 521 may also provide transport for SMS messages between UE 501 and an SMSF (not shown by FIG. 5). AMF 521 may act as SEAF, which may include interaction with the AUSF 522 and the UE 501, receipt of an intermediate key that was established as a result of the UE 501 authentication process. Where USIM based authentication is used, the AMF 521 may retrieve the security material from the AUSF 522. AMF 521 may also include a SCM function, which receives a key from the SEA that it uses to derive access-network specific keys. Furthermore, AMF 521 may be a termination point of a RAN CP interface, which may include or be an N2 reference point between the (R)AN 510 and the AMF 521; and the AMF 521 may be a termination point of NAS (N1) signalling, and perform NAS ciphering and integrity protection.

AMF 521 may also support NAS signalling with a UE 501 over an N3 IWF interface. The N3IWF may be used to provide access to untrusted entities. N3IWF may be a termination point for the N2 interface between the (R)AN 510 and the AMF 521 for the control plane, and may be a termination point for the N3 reference point between the (R)AN 510 and the UPF 502 for the user plane. As such, the AMF 521 may handle N2 signalling from the SMF 524 and the AMF 521 for PDU sessions and QoS, encapsulate/de-encapsulate packets for IPSec and N3 tunnelling, mark N3 user-plane packets in the uplink, and enforce QoS corresponding to N3 packet marking taking into account QoS requirements associated with such marking received over N2. N3IWF may also relay uplink and downlink control-plane NAS signalling between the UE 501 and AMF 521 via an N1 reference point between the UE 501 and the AMF 521, and relay uplink and downlink user-plane packets between the UE 501 and UPF 502. The N3IWF also provides mechanisms for IPsec tunnel establishment with the UE 501. The AMF 521 may exhibit an Namf service-based interface, and may be a termination point for an N14 reference point between two AMFs 521 and an N17 reference point between the AMF 521 and a 5G-EIR (not shown by FIG. 5).

The UE 501 may need to register with the AMF 521 in order to receive network services. RM is used to register or deregister the UE 501 with the network (e.g., AMF 521), and establish a UE context in the network (e.g., AMF 521). The UE 501 may operate in an RM-REGISTERED state or an RM-DEREGISTERED state. In the RM-DEREGISTERED state, the UE 501 is not registered with the network, and the UE context in AMF 521 holds no valid location or routing information for the UE 501 so the UE 501 is not reachable by the AMF 521. In the RM-REGISTERED state, the UE 501 is registered with the network, and the UE context in AMF 521 may hold a valid location or routing information for the UE 501 so the UE 501 is reachable by the AMF 521. In the RM-REGISTERED state, the UE 501 may perform mobility Registration Update procedures, perform periodic Registration Update procedures triggered by expiration of the periodic update timer (e.g., to notify the network that the UE 501 is still active), and perform a Registration Update procedure to update UE capability information or to re-negotiate protocol parameters with the network, among others.

The AMF 521 may store one or more RM contexts for the UE 501, where each RM context is associated with a specific access to the network. The RM context may be a data structure, database object, etc. that indicates or stores, inter alia, a registration state per access type and the periodic update timer. The AMF 521 may also store a 5GC MM context that may be the same or similar to the (E)MM context discussed previously. In various embodiments, the AMF 521 may store a CE mode B Restriction parameter of the UE 501 in an associated MM context or RM context. The AMF 521 may also derive the value, when needed, from the UE's usage setting parameter already stored in the UE context (and/or MM/RM context).

CM may be used to establish and release a signaling connection between the UE 501 and the AMF 521 over the N1 interface. The signaling connection is used to enable NAS signaling exchange between the UE 501 and the CN 520, and comprises both the signaling connection between the UE and the AN (e.g., RRC connection or UE-N3IWF connection for non-3GPP access) and the N2 connection for the UE 501 between the AN (e.g., RAN 510) and the AMF 521. The UE 501 may operate in one of two CM states, CM-IDLE mode or CM-CONNECTED mode. When the UE 501 is operating in the CM-IDLE state/mode, the UE 501 may have no NAS signaling connection established with the AMF 521 over the N1 interface, and there may be (R)AN 510 signaling connection (e.g., N2 and/or N3 connections) for the UE 501. When the UE 501 is operating in the CM-CONNECTED state/mode, the UE 501 may have an established NAS signaling connection with the AMF 521 over the N1 interface, and there may be a (R)AN 510 signaling connection (e.g., N2 and/or N3 connections) for the UE 501. Establishment of an N2 connection between the (R)AN 510 and the AMF 521 may cause the UE 501 to transition from CM-IDLE mode to CM-CONNECTED mode, and the UE 501 may transition from the CM-CONNECTED mode to the CM-IDLE mode when N2 signaling between the (R)AN 510 and the AMY 521 is released.

The SMF 524 may be responsible for SM (e.g., session establishment, modify and release, including tunnel maintain between UPF and AN node); UE IP address allocation and management (including optional authorization); selection and control of UP function; configuring traffic steering at UPF to route traffic to proper destination; termination of interfaces toward policy control functions; controlling part of policy enforcement and QoS; lawful intercept (for SM events and interface to LI system); termination of SM parts of NAS messages; downlink data notification; initiating AN specific SM information, sent via AMF over N2 to AN; and determining SSC mode of a session. SM may refer to management of a PDU session, and a PDU session or “session” may refer to a PDU connectivity service that provides or enables the exchange of PDUs between a UE 501 and a data network (DN) 503 identified by a Data Network Name (DNN). PDU sessions may be established upon UE 501 request, modified upon UE 501 and 5GC 520 request, and released upon UE 501 and 5GC 520 request using NAS SM signaling exchanged over the N1 reference point between the UE 501 and the SMF 524. Upon request from an application server, the 5GC 520 may trigger a specific application in the UE 501. In response to receipt of the trigger message, the UE 501 may pass the trigger message (or relevant parts/information of the trigger message) to one or more identified applications in the UE 501. The identified application(s) in the UE 501 may establish a PDU session to a specific DNN. The SW′ 524 may check whether the UE 501 requests are compliant with user subscription information associated with the UE 501. In this regard, the SMF 524 may retrieve and/or request to receive update notifications on SMF 524 level subscription data from the UDM 527.

The SMF 524 may include the following roaming functionality: handling local enforcement to apply QoS SLAB (VPLMN); charging data collection and charging interface (VPLMN); lawful intercept (in VPLMN for SM events and interface to LI system); and support for interaction with external DN for transport of signalling for PDU session authorization/authentication by external DN. An N16 reference point between two SMFs 524 may be included in the system 500, which may be between another SMF 524 in a visited network and the SW′ 524 in the home network in roaming scenarios. Additionally, the SMF 524 may exhibit the Nsmf service-based interface.

The NEF 523 may provide means for securely exposing the services and capabilities provided by 3GPP network functions for third party, internal exposure/re-exposure, Application Functions (e.g., AF 528), edge computing or fog computing systems, etc. In such embodiments, the NEF 523 may authenticate, authorize, and/or throttle the AFs. NEF 523 may also translate information exchanged with the AF 528 and information exchanged with internal network functions. For example, the NEF 523 may translate between an AF-Service-Identifier and an internal 5GC information. NEF 523 may also receive information from other network functions (NFs) based on exposed capabilities of other network functions. This information may be stored at the NEF 523 as structured data, or at a data storage NF using standardized interfaces. The stored information can then be re-exposed by the NEF 523 to other NFs and AFs, and/or used for other purposes such as analytics. Additionally, the NEF 523 may exhibit an Nnef service-based interface.

The NRF 525 may support service discovery functions, receive NF discovery requests from NF instances, and provide the information of the discovered NF instances to the NF instances. NRF 525 also maintains information of available NF instances and their supported services. As used herein, the terms “instantiate,” “instantiation,” and the like may refer to the creation of an instance, and an “instance” may refer to a concrete occurrence of an object, which may occur, for example, during execution of program code. Additionally, the NRF 525 may exhibit the Nnrf service-based interface.

The PCF 526 may provide policy rules to control plane function(s) to enforce them, and may also support unified policy framework to govern network behaviour. The PCF 526 may also implement an FE to access subscription information relevant for policy decisions in a UDR of the UDM 527. The PCF 526 may communicate with the AMF 521 via an N15 reference point between the PCF 526 and the AMF 521, which may include a PCF 526 in a visited network and the AMF 521 in case of roaming scenarios. The PCF 526 may communicate with the AF 528 via an N5 reference point between the PCF 526 and the AF 528; and with the SW′ 524 via an N7 reference point between the PCF 526 and the SMF 524. The system 500 and/or CN 520 may also include an N24 reference point between the PCF 526 (in the home network) and a PCF 526 in a visited network. Additionally, the PCF 526 may exhibit an Npcf service-based interface.

The UDM 527 may handle subscription-related information to support the network entities' handling of communication sessions, and may store subscription data of UE 501. For example, subscription data may be communicated between the UDM 527 and the AMF 521 via an N8 reference point between the UDM 527 and the AMF. The UDM 527 may include two parts, an application FE and a UDR (the FE and UDR are not shown by FIG. 5). The UDR may store subscription data and policy data for the UDM 527 and the PCF 526, and/or structured data for exposure and application data (including PFDs for application detection, application request information for multiple UEs 501) for the NEF 523. The Nudr service-based interface may be exhibited by the UDR 221 to allow the UDM 527, PCF 526, and NEF 523 to access a particular set of the stored data, as well as to read, update (e.g., add, modify), delete, and subscribe to notification of relevant data changes in the UDR. The UDM may include a UDM-FE, which is in charge of processing credentials, location management, subscription management and so on. Several different front ends may serve the same user in different transactions. The UDM-FE accesses subscription information stored in the UDR and performs authentication credential processing, user identification handling, access authorization, registration/mobility management, and subscription management. The UDR may interact with the SW′ 524 via an N10 reference point between the UDM 527 and the SMF 524. UDM 527 may also support SMS management, wherein an SMS-FE implements the similar application logic as discussed previously. Additionally, the UDM 527 may exhibit the Nudm service-based interface.

The AF 528 may provide application influence on traffic routing, provide access to the NCE, and interact with the policy framework for policy control. The NCE may be a mechanism that allows the 5GC 520 and AF 528 to provide information to each other via NEF 523, which may be used for edge computing implementations. In such implementations, the network operator and third party services may be hosted close to the UE 501 access point of attachment to achieve an efficient service delivery through the reduced end-to-end latency and load on the transport network. For edge computing implementations, the 5GC may select a UPF 502 close to the UE 501 and execute traffic steering from the UPF 502 to DN 503 via the N6 interface. This may be based on the UE subscription data, UE location, and information provided by the AF 528. In this way, the AF 528 may influence UPF (re)selection and traffic routing. Based on operator deployment, when AF 528 is considered to be a trusted entity, the network operator may permit AF 528 to interact directly with relevant NFs. Additionally, the AF 528 may exhibit an Naf service-based interface.

The NSSF 529 may select a set of network slice instances serving the UE 501.

The NSSF 529 may also determine allowed NSSAI and the mapping to the subscribed S-NSSAIs, if needed. The NSSF 529 may also determine the AMF set to be used to serve the UE 501, or a list of candidate AMF(s) 521 based on a suitable configuration and possibly by querying the NRF 525. The selection of a set of network slice instances for the UE 501 may be triggered by the AMF 521 with which the UE 501 is registered by interacting with the NSSF 529, which may lead to a change of AMF 521. The NSSF 529 may interact with the AMF 521 via an N22 reference point between AMF 521 and NSSF 529; and may communicate with another NSSF 529 in a visited network via an N31 reference point (not shown by FIG. 5). Additionally, the NSSF 529 may exhibit an Nnssf service-based interface.

As discussed previously, the CN 520 may include an SMSF, which may be responsible for SMS subscription checking and verification, and relaying SM messages to/from the UE 501 to/from other entities, such as an SMS-GMSC/IWMSC/SMS-router. The SMS may also interact with AMF 521 and UDM 527 for a notification procedure that the UE 501 is available for SMS transfer (e.g., set a UE not reachable flag, and notifying UDM 527 when UE 501 is available for SMS).

The CN 120 may also include other elements that are not shown by FIG. 5, such as a Data Storage system/architecture, a 5G-EIR, a SEPP, and the like. The Data Storage system may include a SDSF, an UDSF, and/or the like. Any NF may store and retrieve unstructured data into/from the UDSF (e.g., UE contexts), via N18 reference point between any NF and the UDSF (not shown by FIG. 5). Individual NFs may share a UDSF for storing their respective unstructured data or individual NFs may each have their own UDSF located at or near the individual NFs. Additionally, the UDSF may exhibit an Nudsf service-based interface (not shown by FIG. 5). The 5G-EIR may be an NF that checks the status of PEI for determining whether particular equipment/entities are blacklisted from the network; and the SEPP may be a non-transparent proxy that performs topology hiding, message filtering, and policing on inter-PLMN control plane interfaces.

Additionally, there may be many more reference points and/or service-based interfaces between the NF services in the NFs; however, these interfaces and reference points have been omitted from FIG. 5 for clarity. In one example, the CN 520 may include an Nx interface, which is an inter-CN interface between the MME (e.g., MME 421) and the AMF 521 in order to enable interworking between CN 520 and CN 420. Other example interfaces/reference points may include an N5g-EIR service-based interface exhibited by a 5G-EIR, an N27 reference point between the NRF in the visited network and the NRF in the home network; and an N31 reference point between the NSSF in the visited network and the NSSF in the home network.

The power management integrated circuitry (PMIC) 725 (also referred to as “power management circuitry 725”) may manage power provided to various components of the platform 700. In particular, with respect to the baseband circuitry 710, the PMIC 725 may control power-source selection, voltage scaling, battery charging, or DC-to-DC conversion. The PMIC 725 may often be included when the platform 700 is capable of being powered by a battery 730, for example, when the device is included in a UE 301 a, 301 b, 401.

In some embodiments, the PMIC 725 may control, or otherwise be part of, various power saving mechanisms of the platform 700. For example, if the platform 700 is in an RRC_Connected state, where it is still connected to the RAN node as it expects to receive traffic shortly, then it may enter a state known as Discontinuous Reception Mode (DRX) after a period of inactivity. During this state, the platform 700 may power down for brief intervals of time and thus save power. If there is no data traffic activity for an extended period of time, then the platform 700 may transition off to an RRC Idle state, where it disconnects from the network and does not perform operations such as channel quality feedback, handover, etc. The platform 700 goes into a very low power state and it performs paging where again it periodically wakes up to listen to the network and then powers down again. The platform 700 may not receive data in this state; in order to receive data, it must transition back to RRC_Connected state. An additional power saving mode may allow a device to be unavailable to the network for periods longer than a paging interval (ranging from seconds to a few hours). During this time, the device is totally unreachable to the network and may power down completely. Any data sent during this time incurs a large delay and it is assumed the delay is acceptable.

A battery 730 may power the platform 700, although in some examples the platform 700 may be mounted deployed in a fixed location, and may have a power supply coupled to an electrical grid. The battery 730 may be a lithium ion battery, a metal-air battery, such as a zinc-air battery, an aluminum-air battery, a lithium-air battery, and the like. In some implementations, such as in V2X applications, the battery 730 may be a typical lead-acid automotive battery.

In some implementations, the battery 730 may be a “smart battery,” which includes or is coupled with a Battery Management System (BMS) or battery monitoring integrated circuitry. The BMS may be included in the platform 700 to track the state of charge (SoCh) of the battery 730. The BMS may be used to monitor other parameters of the battery 730 to provide failure predictions, such as the state of health (SoH) and the state of function (SoF) of the battery 730. The BMS may communicate the information of the battery 730 to the application circuitry 705 or other components of the platform 700. The BMS may also include an analog-to-digital (ADC) convertor that allows the application circuitry 705 to directly monitor the voltage of the battery 730 or the current flow from the battery 730. The battery parameters may be used to determine actions that the platform 700 may perform, such as transmission frequency, network operation, sensing frequency, and the like.

A power block, or other power supply coupled to an electrical grid may be coupled with the BMS to charge the battery 730. In some examples, the power block 730 may be replaced with a wireless power receiver to obtain the power wirelessly, for example, through a loop antenna in the computer platform 700. In these examples, a wireless battery charging circuit may be included in the BMS. The specific charging circuits chosen may depend on the size of the battery 730, and thus, the current required. The charging may be performed using the Airfuel standard promulgated by the Airfuel Alliance, the Qi wireless charging standard promulgated by the Wireless Power Consortium, or the Rezence charging standard promulgated by the Alliance for Wireless Power, among others.

The PHY 910 may still further perform error detection on the transport channels, forward error correction (FEC) coding/decoding of the transport channels, modulation/demodulation of physical channels, interleaving, rate matching, mapping onto physical channels, and MIMO antenna processing. In embodiments, an instance of PHY 910 may process requests from and provide indications to an instance of MAC 920 via one or more PHY-SAP 915. According to some embodiments, requests and indications communicated via PHY-SAP 915 may comprise one or more transport channels.

Instance(s) of MAC 920 may process requests from, and provide indications to, an instance of RLC 930 via one or more MAC-SAPs 925.

A single SDAP entity 947 may be configured for an individual PDU session. In the UL direction, the NG-RAN 310 may control the mapping of QoS Flows to DRB(s) in two different ways, reflective mapping or explicit mapping. For reflective mapping, the SDAP 947 of a UE 301 may monitor the QFIs of the DL packets for each DRB, and may apply the same mapping for packets flowing in the UL direction. For a DRB, the SDAP 947 of the UE 301 may map the UL packets belonging to the QoS flows(s) corresponding to the QoS flow ID(s) and PDU session observed in the DL packets for that DRB. To enable reflective mapping, the NG-RAN 510 may mark DL packets over the Uu interface with a QoS flow ID. The explicit mapping may involve the RRC 955 configuring the SDAP 947 with an explicit QoS flow to DRB mapping rule, which may be stored and followed by the SDAP 947. In embodiments, the SDAP 947 may only be used in NR implementations and may not be used in LTE implementations.

The S1-AP 963 services may comprise two groups: UE-associated services and non UE-associated services. These services perform functions including, but not limited to: E-UTRAN Radio Access Bearer (E-RAB) management, UE capability indication, mobility, NAS signaling transport, RAN Information Management (RIM), and configuration transfer.

The X2AP 963 may support the functions of the X2 interface 312 and may comprise X2AP basic mobility procedures and X2AP global procedures. The X2AP basic mobility procedures may comprise procedures used to handle UE mobility within the E-UTRAN 320, such as handover preparation and cancellation procedures, SN Status Transfer procedures, UE context retrieval and UE context release procedures, RAN paging procedures, dual connectivity related procedures, and the like. The X2AP global procedures may comprise procedures that are not related to a specific UE 301, such as X2 interface setup and reset procedures, load indication procedures, error indication procedures, cell activation procedures, and the like.

The SCTP layer (alternatively referred to as the SCTP/IP layer) 962 may provide guaranteed delivery of application layer messages (e.g., NGAP or XnAP messages in NR implementations, or S1-AP or X2AP messages in LTE implementations). The SCTP 962 may ensure reliable delivery of signaling messages between the RAN node 311 and the AMF 521/MME 421 based, in part, on the IP protocol, supported by the IP 961. The Internet Protocol layer (IP) 961 may be used to perform packet addressing and routing functionality. In some implementations the IP layer 961 may use point-to-point transmission to deliver and convey PDUs. In this regard, the RAN node 311 may comprise L2 and L1 layer communication links (e.g., wired or wireless) with the MME/AMF to exchange information.

In a second example, a user plane protocol stack may comprise, in order from highest layer to lowest layer, SDAP 947, PDCP 940, RLC 930, MAC 920, and PHY 910. The user plane protocol stack may be used for communication between the UE 301, the RAN node 311, and UPF 502 in NR implementations or an S-GW 422 and P-GW 423 in LTE implementations. In this example, upper layers 951 may be built on top of the SDAP 947, and may include a user datagram protocol (UDP) and IP security layer (UDP/IP) 952, a General Packet Radio Service (GPRS) Tunneling Protocol for the user plane layer (GTP-U) 953, and a User Plane PDU layer (UP PDU) 963.

The transport network layer 954 (also referred to as a “transport layer”) may be built on IP transport, and the GTP-U 953 may be used on top of the UDP/IP layer 952 (comprising a UDP layer and IP layer) to carry user plane PDUs (UP-PDUs). The IP layer (also referred to as the “Internet layer”) may be used to perform packet addressing and routing functionality. The IP layer may assign IP addresses to user data packets in any of IPv4, IPv6, or PPP formats, for example.

The GTP-U 953 may be used for carrying user data within the GPRS core network and between the radio access network and the core network. The user data transported can be packets in any of IPv4, IPv6, or PPP formats, for example. The UDP/IP 952 may provide checksums for data integrity, port numbers for addressing different functions at the source and destination, and encryption and authentication on the selected data flows. The RAN node 311 and the S-GW 422 may utilize an S1-U interface to exchange user plane data via a protocol stack comprising an L1 layer (e.g., PHY 910), an L2 layer (e.g., MAC 920, RLC 930, PDCP 940, and/or SDAP 947), the UDP/IP layer 952, and the GTP-U 953. The S-GW 422 and the P-GW 423 may utilize an S5/S8a interface to exchange user plane data via a protocol stack comprising an L1 layer, an L2 layer, the UDP/IP layer 952, and the GTP-U 953. As discussed previously, NAS protocols may support the mobility of the UE 301 and the session management procedures to establish and maintain IP connectivity between the UE 301 and the P-GW 423.

Moreover, although not shown by FIG. 9, an application layer may be present above the AP 963 and/or the transport network layer 954. The application layer may be a layer in which a user of the UE 301, RAN node 311, or other network element interacts with software applications being executed, for example, by application circuitry 605 or application circuitry 705, respectively. The application layer may also provide one or more interfaces for software applications to interact with communications systems of the UE 301 or RAN node 311, such as the baseband circuitry 810. In some implementations the IP layer and/or the application layer may provide the same or similar functionality as layers 5-7, or portions thereof, of the Open Systems Interconnection (OSI) model (e.g., OSI Layer 7—the application layer, OSI Layer 6—the presentation layer, and OSI Layer 5—the session layer).

FIG. 10 illustrates components of a core network in accordance with various embodiments. The components of the CN 420 may be implemented in one physical node or separate physical nodes including components to read and execute instructions from a machine-readable or computer-readable medium (e.g., a non-transitory machine-readable storage medium). In embodiments, the components of CN 520 may be implemented in a same or similar manner as discussed herein with regard to the components of CN 420. In some embodiments, NFV is utilized to virtualize any or all of the above-described network node functions via executable instructions stored in one or more computer-readable storage mediums (described in further detail below). A logical instantiation of the CN 420 may be referred to as a network slice 1001, and individual logical instantiations of the CN 420 may provide specific network capabilities and network characteristics. A logical instantiation of a portion of the CN 420 may be referred to as a network sub-slice 1002 (e.g., the network sub-slice 1002 is shown to include the P-GW 423 and the PCRF 426).

As used herein, the terms “instantiate,” “instantiation,” and the like may refer to the creation of an instance, and an “instance” may refer to a concrete occurrence of an object, which may occur, for example, during execution of program code. A network instance may refer to information identifying a domain, which may be used for traffic detection and routing in case of different IP domains or overlapping IP addresses. A network slice instance may refer to a set of network functions (NFs) instances and the resources (e.g., compute, storage, and networking resources) required to deploy the network slice.

With respect to 5G systems (see, e.g., FIG. 5), a network slice always comprises a RAN part and a CN part. The support of network slicing relies on the principle that traffic for different slices is handled by different PDU sessions. The network can realize the different network slices by scheduling and also by providing different L1/L2 configurations. The UE 501 provides assistance information for network slice selection in an appropriate RRC message, if it has been provided by NAS. While the network can support large number of slices, the UE need not support more than 8 slices simultaneously.

A network slice may include the CN 520 control plane and user plane NFs, NG-RANs 510 in a serving PLMN, and a N3IWF functions in the serving PLMN. Individual network slices may have different S-NSSAI and/or may have different SSTs. NSSAI includes one or more S-NSSAIs, and each network slice is uniquely identified by an 5-NSSAI. Network slices may differ for supported features and network functions optimizations, and/or multiple network slice instances may deliver the same service/features but for different groups of UEs 501 (e.g., enterprise users). For example, individual network slices may deliver different committed service(s) and/or may be dedicated to a particular customer or enterprise. In this example, each network slice may have different S-NSSAIs with the same SST but with different slice differentiators. Additionally, a single UE may be served with one or more network slice instances simultaneously via a 5G AN and associated with eight different S-NSSAIs. Moreover, an AMF 521 instance serving an individual UE 501 may belong to each of the network slice instances serving that UE.

Network Slicing in the NG-RAN 510 involves RAN slice awareness. RAN slice awareness includes differentiated handling of traffic for different network slices, which have been pre-configured. Slice awareness in the NG-RAN 510 is introduced at the PDU session level by indicating the S-NSSAI corresponding to a PDU session in all signaling that includes PDU session resource information. How the NG-RAN 510 supports the slice enabling in terms of NG-RAN functions (e.g., the set of network functions that comprise each slice) is implementation dependent. The NG-RAN 510 selects the RAN part of the network slice using assistance information provided by the UE 501 or the 5GC 520, which unambiguously identifies one or more of the pre-configured network slices in the PLMN. The NG-RAN 510 also supports resource management and policy enforcement between slices as per SLAs. A single NG-RAN node may support multiple slices, and the NG-RAN 510 may also apply an appropriate RRM policy for the SLA in place to each supported slice. The NG-RAN 510 may also support QoS differentiation within a slice.

The NG-RAN 510 may also use the UE assistance information for the selection of an AMF 521 during an initial attach, if available. The NG-RAN 510 uses the assistance information for routing the initial NAS to an AMF 521. If the NG-RAN 510 is unable to select an AMF 521 using the assistance information, or the UE 501 does not provide any such information, the NG-RAN 510 sends the NAS signaling to a default AMF 521, which may be among a pool of AMFs 521. For subsequent accesses, the UE 501 provides a temp ID, which is assigned to the UE 501 by the 5GC 520, to enable the NG-RAN 510 to route the NAS message to the appropriate AMF 521 as long as the temp ID is valid. The NG-RAN 510 is aware of, and can reach, the AMF 521 that is associated with the temp ID. Otherwise, the method for initial attach applies.

The NG-RAN 510 supports resource isolation between slices. NG-RAN 510 resource isolation may be achieved by means of RRM policies and protection mechanisms that should avoid that shortage of shared resources if one slice breaks the service level agreement for another slice. In some implementations, it is possible to fully dedicate NG-RAN 510 resources to a certain slice. How NG-RAN 510 supports resource isolation is implementation dependent.

Some slices may be available only in part of the network. Awareness in the NG-RAN 510 of the slices supported in the cells of its neighbors may be beneficial for inter-frequency mobility in connected mode. The slice availability may not change within the UE's registration area. The NG-RAN 510 and the 5GC 520 are responsible to handle a service request for a slice that may or may not be available in a given area. Admission or rejection of access to a slice may depend on factors such as support for the slice, availability of resources, support of the requested service by NG-RAN 510.

The UE 501 may be associated with multiple network slices simultaneously. In case the UE 501 is associated with multiple slices simultaneously, only one signaling connection is maintained, and for intra-frequency cell reselection, the UE 501 tries to camp on the best cell. For inter-frequency cell reselection, dedicated priorities can be used to control the frequency on which the UE 501 camps. The 5GC 520 is to validate that the UE 501 has the rights to access a network slice. Prior to receiving an Initial Context Setup Request message, the NG-RAN 510 may be allowed to apply some provisional/local policies, based on awareness of a particular slice that the UE 501 is requesting to access. During the initial context setup, the NG-RAN 510 is informed of the slice for which resources are being requested.

NFV architectures and infrastructures may be used to virtualize one or more NFs, alternatively performed by proprietary hardware, onto physical resources comprising a combination of industry-standard server hardware, storage hardware, or switches. In other words, NFV systems can be used to execute virtual or reconfigurable implementations of one or more EPC components/functions.

FIG. 11 is a block diagram illustrating components, according to some example embodiments, of a system 1100 to support NFV. The system 1100 is illustrated as including a VIM 1102, an NFVI 1104, an VNFM 1106, VNFs 1108, an EM 1110, an NFVO 1112, and a NM 1114.

The VIM 1102 manages the resources of the NFVI 1104. The NFVI 1104 can include physical or virtual resources and applications (including hypervisors) used to execute the system 1100. The VIM 1102 may manage the life cycle of virtual resources with the NFVI 1104 (e.g., creation, maintenance, and tear down of VMs associated with one or more physical resources), track VM instances, track performance, fault and security of VM instances and associated physical resources, and expose VM instances and associated physical resources to other management systems.

The VNFM 1106 may manage the VNFs 1108. The VNFs 1108 may be used to execute EPC components/functions. The VNFM 1106 may manage the life cycle of the VNFs 1108 and track performance, fault and security of the virtual aspects of VNFs 1108. The EM 1110 may track the performance, fault and security of the functional aspects of VNFs 1108. The tracking data from the VNFM 1106 and the EM 1110 may comprise, for example, PM data used by the VIM 1102 or the NFVI 1104. Both the VNFM 1106 and the EM 1110 can scale up/down the quantity of VNFs of the system 1100.

The NFVO 1112 may coordinate, authorize, release and engage resources of the NFVI 1104 in order to provide the requested service (e.g., to execute an EPC function, component, or slice). The NM 1114 may provide a package of end-user functions with the responsibility for the management of a network, which may include network elements with VNFs, non-virtualized network functions, or both (management of the VNFs may occur via the EM 1110).

Method 1300 can further include receiving an acknowledgment from the NF that the monitoring of the performance measurement is terminated. Method 1300 can further include transmitting to, for example the consumer device, a response indicating that the threshold monitoring service is terminated.

In some embodiments, the electronic device(s), network(s), system(s), chip(s) or component(s), or portions or implementations thereof, of FIGS. 3-12, or some other figure herein, may be configured to perform one or more processes, techniques, or methods as described herein, or portions thereof.

As described above, aspects of the present technology may include the gathering and use of data available from various sources, e.g., to improve or enhance functionality. The present disclosure contemplates that in some instances, this gathered data may include personal information data that uniquely identifies or can be used to contact or locate a specific person. Such personal information data can include demographic data, location-based data, telephone numbers, email addresses, Twitter ID's, home addresses, data or records relating to a user's health or level of fitness (e.g., vital signs measurements, medication information, exercise information), date of birth, or any other identifying or personal information. The present disclosure recognizes that the use of such personal information data, in the present technology, may be used to the benefit of users.

The present disclosure contemplates that the entities responsible for the collection, analysis, disclosure, transfer, storage, or other use of such personal information data will comply with well-established privacy policies and/or privacy practices. In particular, such entities should implement and consistently use privacy policies and practices that are generally recognized as meeting or exceeding industry or governmental requirements for maintaining personal information data private and secure. Such policies should be easily accessible by users, and should be updated as the collection and/or use of data changes. Personal information from users should be collected for legitimate and reasonable uses of the entity and not shared or sold outside of those legitimate uses. Further, such collection/sharing should only occur after receiving the informed consent of the users. Additionally, such entities should consider taking any needed steps for safeguarding and securing access to such personal information data and ensuring that others with access to the personal information data adhere to their privacy policies and procedures. Further, such entities can subject themselves to evaluation by third parties to certify their adherence to widely accepted privacy policies and practices. In addition, policies and practices should be adapted for the particular types of personal information data being collected and/or accessed and adapted to applicable laws and standards, including jurisdiction-specific considerations. For instance, in the US, collection of, or access to, certain health data may be governed by federal and/or state laws, such as the Health Insurance Portability and Accountability Act (HIPAA); whereas health data in other countries may be subject to other regulations and policies and should be handled accordingly. Hence different privacy practices should be maintained for different personal data types in each country.

Despite the foregoing, the present disclosure also contemplates embodiments in which users selectively block the use of, or access to, personal information data. That is, the present disclosure contemplates that hardware and/or software elements can be provided to prevent or block access to such personal information data. For example, the present technology may be configurable to allow users to selectively “opt in” or “opt out” of participation in the collection of personal information data, e.g., during registration for services or anytime thereafter. In addition to providing “opt in” and “opt out” options, the present disclosure contemplates providing notifications relating to the access or use of personal information. For instance, a user may be notified upon downloading an app that their personal information data will be accessed and then reminded again just before personal information data is accessed by the app.

Moreover, it is the intent of the present disclosure that personal information data should be managed and handled in a way to minimize risks of unintentional or unauthorized access or use. Risk can be minimized by limiting the collection of data and deleting data once it is no longer needed. In addition, and when applicable, including in certain health related applications, data de-identification can be used to protect a user's privacy. De-identification may be facilitated, when appropriate, by removing specific identifiers (e.g., date of birth, etc.), controlling the amount or specificity of data stored (e.g., collecting location data a city level rather than at an address level), controlling how data is stored (e.g., aggregating data across users), and/or other methods.

Therefore, although the present disclosure may broadly cover use of personal information data to implement one or more various disclosed embodiments, the present disclosure also contemplates that the various embodiments can also be implemented without the need for accessing such personal information data. That is, the various embodiments of the present technology are not rendered inoperable due to the lack of all or a portion of such personal information data.
